[1] MPEG Layer II 48KHz 384Kbps Music 0:28
[2] MPEG Layer II 48KHz 256Kbps Music 0:28
[3] MPEG Layer II 48KHz 128Kbps Music 0:28
[4] MPEG Layer II 48KHz 64Kbps Music 0:28
On these musical experiments you will find the same musical excerpt from "Ludwig van Beethoven ~ Symphony No. 5 in C minor, op.67, mov.1 Allegro con brio ~ Berliner Philharmoniker ~ Herbert von Karajan" with 384, 256, 128 and 64 kbps MPEG Layer II 48KHz encoding. [1] 384kbps: it sounds natural. [2] 256 kbps: is quiet indistinguishable from the 384 kbps. [3] 128 kbps: it sounds a little poorly compared to the previous two, tone and sound qualities are little good. [4] there is an awful background noise. The sound is poor, small, unpleasant, and not pure.
